So I have a old Peavey Renown 400, It was loud with the scorpions but very sketchy. It would change vol on its own, pop crack hiss n make noises I dont know how to describe,,lol. I think at sometime it has been wet. I took the speakers out n put them in a 4x12 I had till I recovered it and put new speakers in it. They are in a box now. I was tired of the amp being in the way and unusable so I turned it into a cab. Also some of you can answer this , Can I do anything with the reverb that was in it?
